Abstract:

In this study, some surface properties [color (∆L*, ∆b*, ∆a*, L*, b*, a*, ∆C*, ∆E*, C* and ho), glossiness (parallel (║) and perpendicular (⊥) to fibers at 20o, 60o and 85o) and shore D hardness] that occur after heat treatment applied to coconut (Cocos nucifera L.) wood at 200oC for 3 hours were investigated. In addition, the changes in the surfaces that occurred after the application of different numbered abrasives were also determined in the samples without heat treatment. According to the results of the research, it was determined that the shore D hardness value, gloss values parallel and perpendicular to the fibers at 20o, 60o and 85o, L*, a*, b*, C* parameters decreased and the ho angle increased after the heat treatment. In addition; obtained as ∆H*: 13.87, ∆L*: -14.21, ∆b*: 18.40, ∆a*: -7.93, ∆C*: -14.45, and ∆E*: 24.57. In the surface roughness results, the Ra parameter values were found to be 8.498 µm, 7.429 µm, 6.600 µm, 5.332 µm, 4.188 µm, and 3.452 µm for the abrasives numbered 80, 100, 120, 150, 180 and 220, respectively. It was determined that the roughness parameters decreased with the increase of the sanding number.
